SPRING-HINGE.

`PECIFICATION forming part of Letters Patent No. 500,086, dated June 20, 1893. Application filed January 2, 1889. Serial No. 295,123. (No model.)

.To all whom, t may concern:

Be it known that l, CORNELIUS S. VAN VAGONER, of Brooklyn, in the county of Kings and State of New York, have invented I maintain itin its closed position, but also serve to throw the door fully backward, and to hold it there.

The object of my invention is to secure said well known mode of operation, in a desirably. effective way, by means which are extremely simple and inexpensive, as compared with those employed in 4any prior hinge of this general class of which I have cognizance.

In my hinge, I 4employ leaves which are or may be substantially as heretofore, in all respects relating to their general form, and the arrangement of their laterally projecting ears, and the pintles which connect them. The leaves of my hinges, have also at their inner or coincident edges,inwardlyprojecting loops, to which I apply an elastic band spring which is preferably double, (like a section of rubber tubing,) and said loops may be cut through at one end, so asto receive the band spring, or one or both of them may be solid, so that the spring maybe coupled therewith hy means of pins. A hinge with a spring thus constructed and applied, has a very wide range of movement, between its closed position, and that so called dead point atwhich a door will, stand fully opened and uninu'enced by the spring, but having passed said point, the Spring' will promptly throw the door backward, and hold it ,there To more particularly describe my invention, I will refer to the accompanying drawings in which- Figure l, is a frontview of one of my hinges in its closed position. Fig. 2, illustrates the same in its opened or thrown back position,

but in centralcross section. Fig. 3, illustrates the band spring in side View, and cross section. Fig. 4, illustrates in cross section, one of my hinges, and a band spring applied thereto by means of pins. Fig. 5, illustrates in front View, a hingevwitli the spring applied as in Fig. 4. Fig. 6, illustrates the dead point position of one of my hinges, and shows the wide range of movement, as by a door in swinging from its closed position to said dead point.

The hinge leaves A, and outwardly projecting ears a, are separately pivoted in pairs as heretofore. The loops l) at the inner edges of the leaves, when designed for duty as in Figs. 4 and 5,are precisely as heretofore used by me in hinges embodying spiral springs located longitudinally between the ears, but when used as in Figs. 1 and 2, said loops are slotted or cut at one end, as at b', so that said loops are in fact, hooks.

The band spring B, is preferably composed of line rubber, preferably in the form of a Hattened tube, which can be conveniently applied in either of two ways here shown, and in either case,it can be relied upon fornsnb stantial service for inside duty, and also for one or more ordinary summer seasons when exposed to the weather, as on outside screen doors. Yhen applied as in the hinges shown in Figs. l and 2, it is only necessary to slip the spring, under tension, into the two loops or hooks h, through the slots b', but with the true loops b, of the hinge Figs. 4 and 5, the spring is applied, by passing flattened or folded portions of the spring through the loops, and then inserting the pins c, through the folds of the spring, so that the latter at their two ends will have a firm bearing at the ends of the loops, and securely retain the spring in place, as clearly indicated. It will be readily seen that with the band spring thus applied back of the hinge line, or hinge pivots it will hold the leaves in either of their eXtreme positions, and that a door canu be swung upward of one hundred and thirty degrecs from its closed position, before reaching the point, beyond which it must swing, before the spring will act to throw the door backward, as indicated in Fig. 6.

IOO

I am aware that it is not new to employ a retractile spiral spring applied crosswise of the leaves of a hinge, and arranged to perform the double duty common to this general class of hinges, and hence itis to be understood that my invention is not only restricted to a band spring, but also to its direct application to the inner edges of the leaves, whereby I obtain, in what I believe to be, its simplest and most inexpensive form, a spring hinge, having as wide a range of movement,

between its closed position and the dead point, as is possible in any of the more complex and comparatively expensive forms of spring hinges. v

Having thus described my invention, I claim as new and desire to secure by Letters ,Patent-- The combination of a pair of hinge leaves provided with separately pivoted pairs of projecting ears, and loops or hooks at the inner edges of the leaves, and a band spring back of the pivot line and secured under tension to both of said hooks, and adapted to exercise its force inholding the leaves of the hinge in either of their extremes in position, `due to .their movement on their pivotal c011- nections.
